Abstract (en)
[origin: EP0319874A2] A prism cold shield (10) adaptable to an infrared detector system (25,30) comprises a prism-shaped substrate (10) having an upper portion (12) partially coated with opaque material (15) and a lower portion (20) partially coated with opaque material (11) wherein windows (16) formed by the upper and lower coatings define the field of view for a plurality of infrared detectors (25) thereby cold shielding the detectors in the linear direction of the detector array.
